The long sticks are used to push and set the walking pace. The elbow should never go below a 90° angle. Favour straps that allow you to remain attached to the stick without having to tighten the handle, in order to free the tendons of the hand. Prefer mixed tips (EVA for asphalt and point for roads) to stick to practice, otherwise opt for road tips.
Models: Leki's Traveller Carbon are perfect for Nordic walking. The Black Diamond ones are often collapsible and offer quick deployment; ideal when you don't want to waste time.
